CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 479,990, dated August2, 1892.

Application filed March 11, 1892. Serial No. 424,573. (No model.)

To all whom it may concern.-

Be it known that I, JOHN P. RoLLINs, a citizen of the United States,residing at Cedar Rapids, in the county of Linn and State of Iowa, haveinvented a new and useful Car- Ooupling, of which the following is aspecification.

The invention relates to improvements in car-couplings.

The object of the present invention is to simplify and improve theconstruction of twin-jaw couplings and to enable the knuckles to beoperated from the side of the car.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a car-coupling constructedin accordance with this invention. Fig. 2 is a vertical 1ongitudinalsectional view. Fig. 3 is a horizontal sectional view.

Like numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

1 designates a draw-head, to which is pivoted by a knuckle-pin 2 aknuckle 3, and which is provided with a longitudinal opening 4, andhaving arranged therein a sliding latch-block 5, arranged to engage ashoulder 6 0f the knuckle, to hold the latter in engagement with aknuckle of a twin coupling. The latch-block 5 is slightly curvedthroughout its length and is arranged on inclined ways '7, which arecurved to conform to the configuration of the latch-block, and thelatter is withdrawn from the knuckle to allow the latter to be openedfor uncoupling by a rockshaft 8, mounted on a car J and having an arm10, which is connected with the latchblock by a chain 11 and a bar 12.The bar 12 is pivoted in a bifurcation of the latchblock and extendsthrough a slot 13 of a casing 14:, arranged on the draw-head andreceiving the upper end of the latch-block and adapted to protect thesame when withdrawn from engagement with the knuckle. The upper end ofthe bar 12 is connected by the chain 11 with the arm 10 of therock-shaft, and the outer end of the latter is provided with a handle15, which is arranged at one side of the car to enable cars to beuncoupled Without going between them.

The knuckle is moved outward in position for coupling and to make theuncoupling positive by a sliding bar 16, arranged 011 the bottom of thedraw-head and having its front end disposed between a shoulder or boss17.

the draw-head, and a sliding bar is guided at.

this point by a keeper 24. The outer end of the rock-shaft is providedwith a handle 25, by means of which the sliding bar is reciprocated. Theknuckle is provided with the usual coupling-pin opening 26 and alink-recess 27 to enable the draw-head to be coupled with an ordinarypin and link.

It will be seen that the knuckle may be readily controlled from the sideof a car without necessitating persons going between the cars.

NVhat I claim is f 1. In a car-coupling, the combination of a draw-headhaving a longitudinal opening and provided with slightly-curved inclinedWays,

a knuckle hinged to the draw-head,a curved latch-block arranged on theways and adapted to engage the knuckle, a bar pivotally secured to thelatch-blQck,and a rock-shaft connected with the bar, substantially asdescribed.

2. In a car-coupling, the combination of a draw-head having alongitudinal opening and provided with a slot, a knuckle hinged to thedraw-head, a sliding bar arranged to engage the knuckle and having astem projecting through the slot, and a rock-shaft connected with thestem, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature'in the presence of two witnesses.
